A new study suggests that the timing of a wound affects the speed at which it heals(愈合). Wounds suffered during the day heal around 60 percent faster than those at night.

    The study showed how the body's circadian rhythm(昼夜节律) controlled the healing of wounds{#blank#}1{#/blank#} It tells our bodies when to wake up, eat and sleep in a cycle—a series of activities that repeat themselves day after day{#blank#}2{#/blank#}

    In the study, researchers found that skin cells moved faster to repair wounds suffered during the day. Their findings were published in the journal Science Transnational Medicine.

    The researchers examined cells, mice, and burn injury databases{#blank#}3{#/blank#}Night-time burns—burns suffered between 8 o'clock at night and 8 o' clock the next morning—were 95percent healed after an average of 28 days.

    But after an average of 17 days, daytime burns-burns suffered between 8 o'clock in the morning and 8 o'clock at night—were 95 percent healed{#blank#}4{#/blank#}

    Wounds are very costly to treat{#blank#}5{#/blank#}In Britain's National Health Services, for example, such services cost around $6.56 billion per year. Experts say the high costs result, in part, from a lack of drugs that speed up the closure of wounds.

Being Left-handed in a Right-handed World

    The world is designed for right-handed people, but why does a tenth of the population prefer the left? {#blank#}1{#/blank#}

    The answer to it remains a bit of a mystery. Since scientists have noticed that left-handedness tends to run in families, it's assumed that left-handedness has a genetic (基因的) component to it. {#blank#}2{#/blank#} In fact, identical twins, who share the same genes, can sometimes prefer to use different hands. There are also plenty of theories on what else might determine which hand you write with, but many experts believe that it's kind of random.

    Historically, the left side and left-handedness have been considered a negative thing by many cultures. {#blank#}3{#/blank#} In some areas, the left hand became known as the "unclean" hand. In many religions, the right hand of God is the favored hand. For example, Jesus sits at God's right side. God's left hand, however, is the hand of judgement. Various activities and experiences become rude or even signs of bad luck when the left hand becomes involved. In some parts of Scotland, it is considered bad luck to meet a left-handed person at the start of a journey. {#blank#}4{#/blank#} A person giving directions will put their left hand behind them and even physically try to point with their right hand if necessary. In some Asian countries, eating with the left hand is considered impolite.

    {#blank#}5{#/blank#} People come to realize that left-handedness is natural. People even noticed that many famous people are left-handed  including Benjamin Franklin, Leonardo Da Vinci, and Charlie Chaplin. Some researchers find out that lefties are more creative and can deal with abstract thinking better. The left-handedness is more easily adaptable to the right-handed world as well. Being left-handed is no longer a sad story now; instead, it is a wonderful gift or maybe it is something you should take pride in.

    I'm a survivor of atomic bombing (原子弹轰炸)of Nagasaki, Japan. I was born on December 25, 1944, so when the bombs fell on Nagasaki and Hiroshima, I was only nine months old. My family were not even in the city of Nagasaki. We were outside. {#blank#}1{#/blank#}

    There are three ways that atomic bombs can kill you. One is the blast (冲击波). That knocks down all the buildings nearby. The second is the fireball. {#blank#}2{#/blank#}And those who were touched by the fireball disappeared immediately. And the third way is the radiation (辐射).

    {#blank#}3{#/blank#}

    I remember both my mother and my sister were sick in bed. And when I was six, they died.

    When my sister died, I heard her doctor tell my father that I wouldn't live to see my tenth birthday. So I knew that I was not going to live long. {#blank#}4{#/blank#}Whenever I get a simple cold, I thought this might be the end of my life.

    I also felt that it was wrong for me to stay alive. Why did my sister and my mother, who were wonderful people, had to die? And yet L, who am not worthy, am still alive? {#blank#}5{#/blank#}It kills everything on its way. It kills slowly. and painfully.

    If the United States is attacked with radioactive weapons, millions of people will die. If North

    Korea is attacked, Korea, Japan, part of China and even Russia will be affected I want all nations to come together and start finding a way of getting rid of nuclear weapons altogether.
